Patent: EF-M 18-40 Pancake

By Canon Rumors | January 19, 2014

A patent showing an EF-M 18-40 f/3.5-5.6 pancake has come to light. With this patent a bunch of other optical formulas also appear, such as an 18-55 pancake, 10-20, and a 9-18. We currently have an EF-M 11-22, which is probably rooted from the latter two optical formulas.

A zoom pancake would be a nice addition to the geographically fragmented and oddly marketed EOS M line.
